Note: The MVV test is an exhausting
test. It should not be repeated without
a rest period. Some elderly or ill people
cannot repeat this test even after the
rest period.
'Touch' Back to return to testing and the
current manoeuvre.
Note: If the breathing rate is insufficient
(less than 65 breaths per minute) then
the BR value will be displayed in red – an
MVV value will be calculated and a
message displayed that the MVV result
was extrapolated from a manoeuvre with
a poor breath rate.
